A hornet’s wings, a mere 5 mm long, buzz at 1000 Hz. At a distance of 4 m you hear a sound level of 10 db. (A) If the hornet does this by making the lowest possible standing waves on its wing, what is their wavelength? (explain) (B) What is the speed of the wave on the hornet wing? (C) What is the intensity level 8 m away?

    A closed tube of length 0.60 m is used to create a standing sound wave. Assume that the standing wave created in the tube has the second longest wavelength possible (out of all possible standing waves that fit in the tube). If this tube is then placed on a truck that moves away (at a speed of 90.0 km/hr) from a stationary observer, what frequency does the observer hear?
